COP-HOLDER FOR WlRE-NETTING MACHINES.

SPECIFICATION forming part of Letters Patent No. 554,358, dated February11, 1896. Application filed July 7, 1894. Serial No. 516,804 (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR E. BARLOW, a citizen of the United States,residing at Worcester, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement in aCop-Holder for ire-Netting Machines, of which the following is aspecification, accompanied by drawings forming a part of the same andrepresentin g so much of a netting'machine as is necessary to illustratethe nature of my present invention and its method of operation.

My invention relates to certain improvements in a cop-holder designed tobe used in a wire-netting machine provided with twisting-gears made inhalves and actuated by reciprocating racks in the usual and well-knownmanner common in machines of this class, and ,in the accompanyingdrawings I have not deemed it necessary to show in detail theconstruction and operation of the parts of a wire-netting machine notdirectly concerned in my present invention, as they will be wellunderstood by all persons familiar with wirenetting machinery.

Figure 1 represents an end view of the framework of a wire-nettingmachine shown in section on the plane of one of the bobbin-hold ers, thetwisting-gears, reciprocating racks, and take-up roll being the onlyportions of the operating parts of the machine represented in thedrawings, the bobbin-holder embodying my improvement being shown incentral sectional view. Fig. 2 represents a detached view of thebobbin-holder and twisting-gears, and Fig. 3 represents a centralvertical sectional view of the parts shown in Fig. 2.

Similar letters refer to similar parts in the several figures.

Referring to the drawings, A denotes the framework, B the take-up roll,and C O the reciprocating racks by which the twisting gears are rotated.

D D and D D are bars supported by the framework in which thetwisting'gears are journaled, the twisting-gears being made in halvesand the bars D D being stationary, and the bars D D capable of a slidingmotion by which the one-half of each twistinggcar is shifted in theusual and well-known manner, all the above-described portions of themachine being constructed and operating like the similar portions in thewire-netting machines now in common use.

The lower twistinggears, journaled in the bars D D, are formed of twohalf-sections E and E, the section E having a hole aextending through itto allow a wire a to pass, the

upper end of the section E having a horn a standing obliquely to theaxis of the gear through which the hole a is continued in order to carrythe Wire a away from the copholder. The section E of the lower twisting-.gear extends above the bars D D in the form of a spindle E having itsupper end hollowed or recessed to form a step-bearing E upon which thecop-holder is supported.

The upper twisting-gears j ournaled in the bars D D consist of thehalf-sections F and F, the section F being provided at its lower endwith an oblique horn a through which and the gear-section F is a hole ato receive the bobbin-wire a. The half-section F ex tends below the barsD D, and is recessed to 7 5 form a journal-bearing F for the upper endof the cop-holder, and from the bearing F a hole extends through thehalf-section F to receive the wire Z2 taken from the cop G.

The cop-holder which embodies my present invention is supported at itslower end upon the step E and at its upper end by the journal-bearing Fand it comprises two separate pieces, namely: a bobbin G, upon which thecop of wire G is wound and consisting of a piece of pipe G provided witha conical head G the outer surface of the hollow pipe G and head G beingpreferably slightly corrugated to prevent the slipping of the wire woundthereon. The lower end of the pipe G 0 is provided with a steel block Gwhich rests in the step-bearing E WVithin the pipe G is placed a spindleH, upon which the bobbin G is capable of turning freely, the spindle Hforming a support for the upper end of the 5 bobbin. The spindle I-Ipasses through and is attached to a head H, the upper end of the spindlebeing inclosed and capable of rotating freely within the journal-bearing F Attached to the head H is a cylindrical hood H provided with a slotH The upper end of the spindle H is hollow and is provided with a hole Hcommunicating with the interior of the spindle. For convenience ofconstruction I usually make the spindle II from a piece of gas or steampipe and bore the hole H communicating with the interior of the pipe.From the j ournal-bearing F a hole b extends through the gear-section Fin alignment with the axis of the spindle H. The hood II extends fromthe head II downward over the cop G, and the cop-wire b is taken fromthe cop G through the slot II in the hood, through the hole H to theinterior of the spindle II, and then upward through the hole I), thecopwire I) being delivered at the upper end of the ear-section Fcontiguous to and parallel with the bobbin-Wire a, so they will betwisted together by the rotation of the twisting-gears in the usual andwell-known manner.

The twisted fabric is carried over the take up roll 13, which isintermittently rotated at the end of each twisting operation to draw thewires a b upward in order to form a succeeding series of twists. As thecop-wireb is drawn up it will be unwound from the cop G, either by theindependent rotation of the bobbin "G due to the draft of the wire onthe bobbin or by the independent rotation of the head II due to thedraft of the wire against the edge of the slot H the bobbin G and hood Hbeing capable of rotating independently of 'each other.

The lower end of the bobbin G and the upper end of the spindle E areinclosed by a sliding sleeve I, which is supported upon the end of aspiral spring I, having its lower end resting upon the upper end of the'gear-section E, the sliding sleeve I serving to break the joint betweenthe spindle E and the lower end of the bobbin and hold the end of thebobbin upon the step-bearing. WVhen it is desired to remove the-end ofthe bobbin from the step-bearing, the sleeve I can be moved downward,compressing the spiral spring I.

The sliding sleeve I and spiral spring I are inclosed by an outersliding sleeve J, which rests upon the upper end'of the gear-section Eand is capable of being raised over the bobbin G in order to allowaccess to the sleeve I.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a wire-netting machine, the combination with upper and lowertwisting-gears, of a cop-holder comprising a bobbin supported at itslower end in a step-bearing on the lower of said twistingears and havingits upper end journaled on a spindle, a spindle entering said bobbin andcapable of turning therein and having its upper end journaled in theupper of said twisting-gears, and a hood carried by said spindle andprovided with a slot, substantially as described.

2. In a wire-netting machine, the combination of the gear-sections E andE, said section E having a step-bearing, a bobbin G supported bysaidstep-bearing, gear-sections I and F", said section I" having a journaledbearing F a hollow'spindle I-I having its upper end journaled in saidbearing-and its lower end journaled in said bobbin, and a hood IIcarried by said spindle and having a slot H substantially as described.

3. The combination of gear-section E having a spindle E and astep-bearing E, a bobbin G supported by said step-bearing, a slidingsleeve I extending over the end of said spindle E and said bobbin, and aspring I supporting said sleeve, substantially as described.

4. In a wire-netting machine, the combination of a gear-section E havinga spindle and a step-bearing E, a bobbin G supported by said step'bearing, a sliding sleeve I, a spring I supporting said sleeve, and anouter sleeve .I inelosing said sleeve I and spring I, substantially asdescribed.

Dated this 4th day of July, 1894.
